Why go
Thermopolis is one of those places that many travelers happen to discover – and often stay longer than planned.The small town lies picturesquely on the Bighorn River and is known for its largest natural hot water springs in the world. Unlike many thermal resorts, the public pools are free of charge here and invite you to relax after long rides.
In addition to the thermal springs, Thermopolis offers surprisingly many other highlights: dinosaur finds, colorful canyons, wildlife observations and a relaxed atmosphere far away from the big tourist streams. For RV travelers, Thermopolis is an ideal stopover between Cody, Bighorn Mountains and Casper.

Hot Springs State Park
Hot Springs State Park is the heart of Thermopolis. More than three million liters of mineral-containing thermal water flow out of the earth daily and feed several natural terraces as well as pools.
Particularly impressive are the coloured lime terraces, which were created by thousands of years of mineral deposits.
Insider tip
Many visitors stay only with the swimming pools. A walk over the raised wooden steps leads, however, to the most beautiful viewpoints on the steaming terraces.
Free thermal bath
A special feature of Thermopolis is the public thermal bath, which is available to all visitors free of charge.
The water is cooled down to a pleasant bath temperature and is perfect for relaxing after a long day of travel.
RV tip
After several days on the road there is hardly a better place to relax muscles and back.

Internet & Mobile
In the city, mobile communication is good. At Hot Springs State Park, there can be some weaker signals.
Avoid frequent errors
The thermal water is very mineral-containing – don't wear sensitive jewellery in the water.
In summer, an early visit to the thermal pools is recommended as they are well attended in the afternoon.
The mineral terraces are sensitive. Please stay on the marked paths and wooden bridges.
Our recommendation
Thermopolis is the ideal place to relax after several days of hiking tours and long rides. The combination of free thermal springs, impressive nature and a relaxed small town atmosphere makes the place a real secret tip in Wyoming.
Many travelers just pass by on the way between Cody and Casper. We recommend the opposite: take a day, bathe in the warm springs, stroll through Hot Springs State Park and enjoy the sunset on the Bighorn River. Often it is exactly such unexpected places that make a trip unforgettable.
